Spaceborne GPS Internet Site

In the summer of 1996 I began work on an Internet site designed to describe the developments in spaceborne GPS (SGPS) - my research area. SGPS (as I like to call it) involves the use of Global Positioning System (GPS) receivers for positioning, navigation, and timing in space. The site describes SGPS, SGPS applications, a mission directory, descriptions of SGPS orbit determination, real-time orbit determination, attitude determination, relative positioning, spacecraft system clock synchronisation, a listing of SGPS receivers, and other sites with SGPS resources.
